METHODS Observational case report. RESULTS A 6-year-old female presented for a routine examination. Visual acuity was 20/20 bilaterally. Dilated fundus examination was normal in the right eye. Dilated fundus examination of the left eye showed a wedge-shaped area of hypopigmentation in the temporal macula. Optical coherence tomography macula of the left eye showed outer retinal cavitation with segmentation of the foveal retinal pigment epithelium into a superficial fluffy zone and a deeper hyperreflective zone. CONCLUSION This case helps contribute to the growing body of the torpedo maculopathy literature that may reveal different stages of the same disease evolving over time.PURPOSE To study intraocular pressure (IOP) outcomes after surgery for rhegmatogenous retinal detachment in Schwartz syndrome. METHODS We reviewed records of 32 eyes of 32 patients with Schwartz syndrome (patients with rhegmatogenous retinal detachment, IOP above 21 mmHg, and open angles without angle recession, chronic steroid use or other secondary causes of increased IOP) who had undergone surgical treatment consisting of scleral buckling or vitrectomy. Intraocular pressure, number of medication, best-corrected visual acuity were compared at baseline and postsurgery visits and also studied association of various factors on long-term IOP. RESULTS The median duration of rhegmatogenous retinal detachment was 2 months, and the inter quartile range was 1 to 12 months. Follow-up was 15 months (inter quartile range 7-33 months). Sixteen (50%) had prior ocular trauma. Baseline IOP was 35 ± 8 mmHg, and 12% (4/32) of patients were on IOP-lowering medication at presentation. At the final visit, mean IOP was 17 ± 6 mmHg and 59% patients (19/32) required additional IOP-lowering medication or surgery for IOP control. CONCLUSION Surgical management of rhegmatogenous retinal detachment resulted in significant reduction in IOP. At the final visit, 41% did not require any IOP-lowering medication or surgical intervention for IOP control.PURPOSE To compare the morphological characteristics of subretinal fibrosis in late age-related macular degeneration using multicolor (MC) imaging, color fundus photography (CFP), and ultra-widefield CFP (UWFCFP). METHODS Thirty-two eyes of 31 patients diagnosed with subretinal fibrosis complicating exudative age-related macular degeneration were included. Included eyes were imaged by MC, CFP, and UWFCFP. The overall ability to visualize fibrosis, its margins, and dissimilarity with surrounding atrophy was graded using a score (0 not visible, 1 barely visible, 2 mostly visible, and 3 fully visible) by two readers. Area of fibrosis was calculated. Scaling, lesion colocalization on all three imaging techniques, and area measurements were performed using ImageJ. RESULTS Ninety-six images of 32 eyes were graded. The average area of fibrosis was 14.59 ± 8.94 mm for MC, 13.84 ± 8.56 mm for CFP, and 13.76 ± 8.79 mm for UWFCFP. Fibrosis was fully visible in 87.5% of cases using MC and 50% using CFP and UWFCFP. Fibrosis' margins were sharply defined in 40.6% of eyes with MC, 15.6% and 9.4% with CFP and UWFCFP, respectively. Multicolor imaging provided superior distinction between fibrosis and atrophy (100% for MC vs. 13.4% for CFP and 33.3% for UWFCFP). The inter- and intra-reader agreement was high for all measurements (P less then 0.0001). CONCLUSION Multicolor technology allows for improved visualization and analysis of subretinal fibrosis when compared with CFP and UWFCFP, especially when surrounding atrophy is present.BACKGROUND The objective of this study was to investigate the serum concentrations of olanzapine in relation to age, sex, and other factors in Chinese patients aged between 10 and 90 years. METHODS Data for 884 olanzapine patients, deposited between 2016 and 2017, were retrieved from the therapeutic drug monitoring (TDM) database of the Affiliated Brain Hospital of Guangzhou Medical University. The effects of covariates on serum olanzapine concentration, dose-normalized concentration (C/D ratio), and normalized concentration (C/D/weight) were investigated. RESULTS Generally, males had lower olanzapine concentration, C/D ratio, and C/D/weight than females (p less then 0.001). Smoking and drinking reduced olanzapine concentration, C/D ratio, and C/D/weight (p less then 0.001). Co-administration with valproate decreased olanzapine concentration, C/D ratio, and C/D/weight by about 16%, 30% and 40%, respectively (p less then 0.001). Patients younger than 60 years had higher olanzapine concentrations (p less then 0.05), but lower C/D ratios and C/D/weight (p less then 0.001) than patients older than 60. Age was correlated with olanzapine concentration (r = -0.082, p less then 0.05), C/D ratio (r = 0.196, p less then 0.001), and C/D/weight (r = 0.169, p less then 0.001). Sample timing post-dose and diagnostic factors also contributed to the olanzapine concentrations. Multiple linear regression analysis revealed significant influences of dosage, age, sex, valproate comedication, smoking, post-dose interval, and schizophrenia (vs bipolar affective disorders) on serum olanzapine concentrations. CONCLUSIONS The metabolism of olanzapine may be altered by several factors. Patients characterized with a combination of factors may benefit from TDM for the adjustment of olanzapine dose to minimize adverse reactions.The authors present the case of a critically ill morbidly obese patient (body mass index (BMI), 51.2 kg/m) who suffered from methicillin-resistant Staphylococcus epidermidis (MRSE), and Candida albicans bloodstream infections. Initial treatment with caspofungin and daptomycin was deemed inappropriate, as blood cultures remained positive for both isolates after 14 days. The clinical pharmacological consultant suggested adding fluconazole and ceftobiprole to the ongoing antimicrobial therapy, as well as starting a real-time TDM program of daptomycin, ceftobiprole, and fluconazole, aimed at optimizing plasma exposures. Punctual MIC knowledge on the clinical isolates allowed attainment of the desired pharmacodynamic efficacy targets. Within few days, the patient greatly improved, as blood cultures became negative, and the inflammatory markers decreased to near normal values. This is a proof-of-concept of the importance of a TDM-based multidisciplinary approach in the proper management of complex antimicrobial therapy in special populations.
